Q+B=13. When B+3=0

You have 2 separate equations.

First solve the 2nd equation for B:

B +3 = 0

Subtract 3 from both sides:

B +3 - 3 = 0-3

Simplify:

B = -3


Now we have a value for B, we can replace b with -3 in the first equation and solve for Q:


Q + -3 = 13

Add 3 to each side:

Q + -3 + 3 = 13+3

Simplify:

Q = 16


So you have Q = 16 and B = -3

Question

SHOW YOUR WORK Q+B=13. When B+3=0

Answer:

16 + (-3) = 13

Step-by-step explanation:

find b

B + 3 = 0

B = -3

now we have the expression:

Q + (-3) = 13

Q = 13 + 3

Q = 16

check

16 + (-3) = 13

16 = 16

33. The perimeter of a room is 22m.lf<br> the length of the room is 6.5m,<br> what is its width?
vredina [299]

The formula for perimeter is 2(Length) + 2(width)

Fill in the known information:

22 = 2(6.5)+ 2(width)

Simplify:

22 = 13 + 2(width)

Subtract 13 from both sides:

9 = 2(width)

Divide both sides by 2:

Width = 4.5m

What is 2X to the power of 3 divided by -8X to the power of 4?
PIT_PIT [208]

Answer: 8 = 23 (-8)4 = (23)4 = 212

1/(2048x)

Step-by-step explanation:Negative number raised to an even power is positive

For example let's look at (-7)6 , where (-7) , a negative number, is raised to 6 , an even exponent :

(-7)6 can be written as (-7)•(-7)•(-7)•(-7)•(-7)•(-7)

Now, using the rule that says minus times minus is plus, (-7)6 can be written as (49)•(49)•(49) which in turn can be written as (7)•(7)•(7)•(7)•(7)•(7) or 76 which is positive.

We proved that (-7)6 is equal to (7)6 which is a positive number

Using the same arguments as above, replacing (-7) by any negative number, and replacing the exponent 6 by any even exponent, we proved which had to be proved

Dividing exponential expressions :  x3 divided by x4 = x(3 - 4) = x(-1) = 1/x1 = 1/x

Final result :

1/2048x
